Teva sildenafil is a generic version of Viagra that treats erectile dysfunction (ED) and heart conditions like pulmonary arterial hypertension (PAH). Viagra is so popular that its name has become synonymous with ED treatment — just like Ziploc has with plastic bags. It’s been a wild success since it entered the market in 1998. But in 2013, Teva Pharmaceuticals made a generic form of sildenafil to compete with Viagra. After a long court battle and approval by the Food and Drug Administration (FDA), Pfizer paid Teva to not release their generic form until 2017. So, here’s what you should know about it — how it works, how it compares to Viagra, and what precautions you should take. This means that it helps block the PDE5 enzyme that affects certain muscles in your penis and heart. PDE5 can restrict blood flow to blood vessels in the spongy penis tissue called corpus cavernosa. This tissue helps your penis get erect when you’re aroused. During arousal, it becomes filled with blood.

Archived from the original on 10 March 2013. Teva sildenafil and other similar medications help stop PDE5 from restricting blood flow into these blood vessels. By doing this, it helps your penis get enough blood to maintain an erection. PAH can cause smooth muscle in your lungs to become inflamed and restrict blood flow in certain lung arteries. PDE5 inhibitors like Teva sildenafil help dilate these arteries and reduce your blood pressure. You can get Teva sildenafil with a prescription from your doctor. It comes in the following tablet sizes: It also comes as an oral suspension (liquid form) or an injection given by your doctor. Teva sildenafil is prescribed to people who have difficulties having an erection or staying erect throughout a sexual encounter. This medication is very similar to Viagra and works to help with erectile dysfunction by inhibiting PDE5, an enzyme that can cause the penis to not become erect or lose an erection prematurely. Since Teva sildenafil is available as a generic drug, one of the major benefits over Viagra is its lower cost. This means that a person experiencing ED can receive many of the benefits of taking Viagra at a reduced cost.

This is especially beneficial if prescription Viagra is outside of a person’s budget. While a majority of Teva sildenafil users take the medication to treat ED, it is also approved to treat pulmonary arterial hypertension (PAH) as well. Your doctor may choose to prescribe it for treating PAH, even when symptoms of ED are not present. Additionally, research shows Teva sildenafil may be effective in Teva sildenafil only works properly if you take it about an hour before you have sex.

You need to be sexually aroused to get erect and for the medication to sustain the erection. Teva sildenafil takes effect about 30 to 60 minutes after you’ve taken it. Like other medications, the effects of Teva sildenafil might be delayed if you eat right before you take it. This is because food competes for absorption from the stomach into the bloodstream. Spoiler alert: There’s no real difference between Viagra and Teva sildenafil. Remember that the name of the drug sold as Viagra is sildenafil citrate. The difference in names is really just for marketing reasons. The main functional ingredient is the same. Teva sildenafil is a generic version of Viagra that’s sold and branded by a different company. This means that it’s typically sold for much lower prices since no marketing dollars are needed to sell it. There are also some medical reasons for the distinction between Teva sildenafil and Viagra.

Sildenafil and Viagra are both used to treat erectile dysfunction, but sildenafil can also be prescribed to treat PAH and reduce blood pressure in the lungs. Viagra is currently only legally approved for use to treat ED. There’s also a visual difference in the two. Viagra is infamous for being the “little blue pill.” But Teva sildenafil tablets are simply off-white or white in color. Before you decide to use Teva sildenafil, talk to a doctor.
